Abstract

This study aims to assess the environmental impact of wastewater discharges from FERMENCAM. Effluent and wastewater samples were collected respectively at the plant outlet and in the receiving environment, and physico-chemical analyses carried out revealed an organic pollution with a high pollution load that can be observed by phosphate levels in water at the plant outlet. Biochemical oxygen demand (BOD5) is high at the plant outlet (20300 mg of O2 / L) and 16200 mg of O2 / L are found in the receiving environment. The BOD5/COD (chemical oxygen demand) ratio of effluents discharged by FERMENCAM and that of the receiving environment is 0.90. This value is higher than 0.5, meaning that the organic matter of both effluents is highly biodegradable. The results show that the increase in conductivity and decrease in total dissolved salts are due to an excessive mineralization of organic matters. The results show that the chlorophyll synthesis in Amaranthus viridis leaves is linked to the quality of the environment, and that is why such leaves can easily adapt to the polluted environment. In short, the wastewater impact on water quality of the receiving environment is evident, and these data will allow better environmental protection, thus promoting the development of various waterfront activities. In addition, the need for sustainable wastewater management (wastewater treatment plants, pre-treatment of industrial waters and sensitization) in the study area proves to be vital and urgent in order to improve wastewater quality and contribute to improving the state of the environment.
